Moon dial not moving

Not sure how to resolve this but the moon phase gear isn't turning. The clock runs and reliably. Any suggestions?

The moon phase operation is only two gears and a friction clutch. Make sure that both gears can move freely. Touch the gears and they should move slightly. Test the friction clutch by manually rotating the moon dial by reaching behind the main dial. There should be a small amount of resistance.


Another possibility is that you need to wait longer to see the moon phase rotate. The moon dial makes one complete rotation every 59 days. This gives a full moon cycle of 29.5 days.
